About me

I build scalable systems that turn complex ideas into reliable products.

Clean architecture, modular design, and maintainable code are a personal standard. I code with scalability and reliability in mind, from database schema to API design to frontend state management.

B2B SaaS · Event Management Platform

PlaniT

A multi-tenant SaaS platform built for event organizations to manage their entire operation — from vendor sourcing and team coordination to budget tracking and client management — all under one role-aware interface.

  • Multi-tenant architecture with org-level data isolation — each organization's data is fully scoped and never bleeds across tenants
  • JWT access tokens stored in memory with silent renewal via Axios interceptors on 401 — no token exposure in localStorage
  • Granular RBAC system — UI components, routes, and API actions all gate conditionally on the authenticated user's role
  • Live financial engine with running budget totals, over-budget alerts, receipt storage via Supabase, and a full expense audit log with user attribution

Web Performance Analysis Platform

MetriQ

A developer tool that audits any public URL against Google PageSpeed Insights, generates AI-powered fix summaries, and lets you benchmark your site against competitors — all exportable as a PDF report.

  • Google PageSpeed Insights integration for both mobile and desktop — surfaces Core Web Vitals, accessibility scores, and SEO signals
  • AI-generated audit summaries via OpenRouter + DeepSeek — translates raw Lighthouse data into plain-English action points
  • Side-by-side competitor comparison with Recharts visualizations — benchmark multiple URLs in a single view
  • OAuth via Google and GitHub, persistent report history, PDF export, and full dark/light mode support
